RUGGEDNESS STUDY

The ruggedness of an analytical method is the degree of reproducibility of the test

results obtained by the analysis of the samples from same lot under a variety of normal test

conditions (i.e. different laboratories, analysts, days & Instruments).

The ruggedness of assay method of Methylsalicylate in Movsar Gel shall be studied

by analyzing the samples from same lot by two different analysts from same laboratory or at

two different laboratories by two different analysts on two different days.
